I think that since everyone else was coming up with motion controllers, Nintendo felt they had to do something. If it ever is released and works I'm sure Sony & Microsoft will have one in a couple years.

Wow, check out the Mr. Negatives in here, this btw isn't really anything new. Nintendo released a simerlar device on the N64 for "Panic Tetris". Rather than attaching it to your finger, you had a clip that went on your ear, and back to the memory card port on the controller. The idea is that it trains you to stay calm, because if you stress out the Tetris pieces start to fall really fast.

I can come up with great ideas for this device, say for example an American style RPG, if you can stay calm you can lie to NPC characters, Online games can use it so that the facial expression of your character changes depending on your emotions and it can be used as a funny gimmick such as you have to stress out in order to make Mario become Fire Mario.

Why would you be anything but calm while playing an RPG? I could definitely see such a device being put to interesting uses, but if you have to put your finger in it like that, you will be limited to only holding the controller with the other hand, judging from how the thing looks. I can't imagine what Nintendo has in mind.

I can come up with some fun game ideas for it. It's perfect for horror games. Your playing the game and the tenser you get, the harder and scarier the game will get, you have to keep your cool in a scary environment. And when you beat the game and go for a second round, the mechanic switches around so if the game isn't scaring you the A.I. will give you a hard time.

To be honest, I really loved Nintendo E3 2009. But what I didn't like about it was this, the low point in the conference. This is an unecessary device for sure, at least Wii MotionPlus and WiiSpeak gave what we wanted, Vitality Sensor doesn't. What in the world where they thinking?

It isn't necessarily a bad device. But it is a bad press move to show a device without any software to validate it. Not only were there no readily available applications of the device, but Iwata didn't even seem that confident in his speech about it. Color me skeptical, but I'm not ready to call the machine pointless. They must have something in mind, or they would not have made it.
